Babysitter Needed for my Children

I'm looking for after-school help with my two girls, ages 6 & 9, two to three times per week, Tuesday, Wednesdays, and Thursday from 3:30-6:30 p.m. We need help picking up the girls from school nearby, serving snacks, and driving to practices. We could also use help with a bit of light housekeeping, such as cycling the girls' laundry. We have a friendly dog (golden doodle) and a car you could use for driving the kids. We could also use help on Arlington Public School early release & some holidays, if possible.
